COIN-OPERATED VENDING DEVICE.

SPECIFICATION forming art of Letters Patent No. 455,948, dated July 14,1891.

Application filed January 2, 1891.

Serial No. 376,477. (No model) To aZZ whom it may concern:

Be it known that I, HAIG D. MUGERDITCH- YAN, a subject of the Sultan ofTurkey, residnew and useful Improvements in Coin-Operated VendingDevices, of whichthe following is a specification.

My invention relates to that class of vending apparatus which are heldfrom operation by devices which can only be released by the size, andmore especially to improvements in such coin controlled apparatus as areintended for use in delivering from a closed receptacle or box sheets ofpaper, such as accident-insurance policies, tickets, postal-cards,stamped envelopes, and the like.

My invention consists in the devices and combinations of deviceshereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view. Fig. 2 is anelevation on the line 2 2 of Fig. 1, looking in the direction of thearrow 2. Fig. 3 is a transverse sectional elevation to the left of theline 3 3 of Fig. 1. Fig. 4 is a sectional elevation on the line 4 l ofFig. 1 and looking in the direction indicated by the arrow 4. Figs. 5 to8, inclusive, are detail views of a feed-roller and parts of itsoperating mechanism.

In the drawings, 9 indicates a box or casing having a removable cover10. Within the box are the vertically-placed guide-plates 11, betweenwhich moves the spring-supported follower 12, on which are placed thesheets 13, which may be postal-cards, tickets, insur ance-policies, orother articles, the sheetsbeing supported upon each other and normallyheld up by the spring-pressed follower, so that the upper one ismaintained in contact with a delivery-roller 14, loosely mounted upon anaxle l5, journaled in brackets 16. Upon the outer end of roller 14 isfixed a ratchet-wheel 16 engaged by a pawl 17, which prevents thebackward rotation of the roller. (See Figs. 3 and 7.) Upon the inner endof the roller is secured a ratchet-wheel 18, and secured upon the axleis a ratchet-wheel 19, carrying a pivoted pawl 20, normally carried toengage the teeth of ratchet-wheel 18 by means of the Spring 21.

In the operation of delivering, the ratchet 19 is rotated in thedirection indicated by the arrow in Fig. 8, and is locked with theroller bythe pawl 20, so as to cause the forward rotation of said rollerand the delivery .of the topmost sheet. In the reverse movement of theratchetwheel 19 the roller is locked against rotation by the pawl 17.

The means for rotating the delivery-roll comprise a slidable rack-bar22, moving in ways formed in the brackets 16 23. The rackbar 22 isnormally retracted by a spring 24, and it carries on its side toward itsrear end the angular arms 25, the rear edges of which lie parallel tothe plane of the coin-chute 26, the upper end of which registers with asuitable coi'n-aperture in the lid of the box. A plate 27 hasbifurcations 28 thereof projected beneath the lower end of thecoin-chute and arrests the coin as it falls when the coin is of theproper size, but allows a coin of less size to fall through.

29 is an operating-plunger which slides in ways formed in the standards30. The forward end of the plunger projects outside the box or casing,and a spring 31, connected at one end to the plunger and at the other tothe casing, normally tends to retract the plunger. This plunger hasprojected from its side an arm 32, which when the plunger is retractedlies in a plane parallel to the opening in the chute and on the oppositeside thereof from the arms 25. hen a coin of proper size is deposited inthe chute, it comes to rest upon the bifurcations 28 between the arms 25and 32, and a pull on the plunger 29 will clamp the coin between saidarms, thereby locking the rack-bar and plunger together.

The forward movement of the rack-bar rotates the roller by means of theratchet mechanism before described, and the roller delivers the topmostof the sheets through a delivery-aperture in the front of the casing. In

order to release the coin I provide a stop to arrest the rack-bar beforethe completionof the return movement, which is eifected by the springs.This stop mechanism comprises a dog 34, carried by a rock-shaft 35,which supports at its opposite end a cam-lever 36. In the normalcondition of the parts the dog 34 and cam 36 project beneath and in thevertical plane of the rear ends of the rack-bar and operating-lever,respectively. A spring 37,

move back the rack-bar is arrested by the en gagement of the dog and theoperating-plunger moving on releases the coin. When theoperating-plunger engages the cam, it causes the release of the dog andpermits the spring 7 to return the rack-bar to its normal position.

I do not intend to limit my invention to the precise structural featuresor arrangement of parts illustrated in the drawings-for example, theform and location of the springs described might be varied. Instead ofemploying the rack 38, the dog 3a might be made to engage the end of therack-bar at the close of its forward movement and hold it against returnuntil said dog is withdrawn by the,

engagement of the operating-plunger with the cam. I prefer to arrest therack-bar at the limit of its forward movement to permit theoperating-plunger to return, so as to disengage the coin, as by thismeans more than a single operation of the roller for the delivery of asheet is prevented.

I claim- 1. In a coin-operated vending device, the combination, withsheetdelivery mechanism, of a slidable bar adapted to actuate thedelivery mechanism and having a portion of its surface corresponding tothe length of its movement provided with rack-teeth, a spring to retractsaid bar, an operating plunger adapted to be locked to the bar by theinsertion of a coin, a rock-shaft having on one end thereof a dog toengage the slidable bar and upon the other end a cam located in the pathof the operating-plunger, and a spring normally tending to force the doginto engagement with the bar, whereby the slidable bar is dogged at alltimes during its forward movement and is released upon the backwardmovement of the operating-plunger, either before or after the completionof a full stroke, substantially as described.

2. In a coin-operated sheet-vending apparatus, the combination, with theinclosing casing, of verticallydisposed guideplates therein,aspring-pressed follower upon which the sheets are superposed,adelivery-roller against which the sheets are maintained, a ratchetmechanism connected with said roller and adapted to permit the rotationof thelatter in one direction only, a sliding rack-bar in gear with theratchet mechanism, and an operating-plunger adapted to be locked withthe rack-bar by the insertion of a coin, and means for arresting thebackward movement of the rack-bar to permit the release of the coin andfor releasing said bar after the release of the coin, substantially asdescribed.

In acoin-controlled sheet-delivery apparatus, a spring-supportedfollower upon which the sheets are superposed, a delivery-roller mountedabove the sheets and adapted to engage them, said roller being looselymounted on its axle, ratchet mechanism secured to each end of saidroller, a pawl engaging one of said ratchets and adapted to prevent thebackward rotation of the roller, and a driving-gear secured with theaxle and adapted to be locked with the roller to secure its forwardrotation, a rack-bar enmeshed with the drivingear, a spring to retractsaid rackbar, and an operating-plunger adapted to be locked with therack-bar by the insertion of a coin, subtantially as described.
